The increase in dross buildup insulates the metal from the heat and will require harder firing; this will again generate more dross. It‟s a vicious cycle! As previously stated, movement of the molten metal through stirring will also help prevent these hot spots. Furnace Skimming Skimming removes most of the dross from the furnace allowing for more efficient melting and temperature control. When and how to skim is very important and will affect the overall aluminium recovery that is experienced from dross that is removed.

Prasad 33 Opportunities for CO2 Emission Reduction It appears from this analysis that cast house activities can make up to 5% of total GHG emissions associated with primary aluminium production. Reduction in dross generation and an increase in melt recovery seem to be a high priority in terms of reducing GHG for cast house operations for both case and case 2. Increasing furnace energy efficiency will also lead to reduced GHG emissions. , eliminate the furnaces and the energy and materials consumed there.
